OBJECTIVES This study investigated the vaginal colonization rate of Streptococcus agalactiae (group B streptococci, GBS) in an antenatal population in a maternity hospital. SUBJECTS AND METHODS Anal, vaginal and combined anal and vaginal specimens were obtained from 110 pregnant women (mean age 30.7 +/- 5.5 years) at 35-37 weeks of gestation, using a commercially prepared culturette, and tran...

Group B Streptococcus (GBS) is still not routinely screened during pregnancy in Brazil, being prophylaxis and empirical treatment based on identification of risk groups. This study aimed to investigate GBS prevalence in Brazilian pregnant women by culture or polymerase chain reaction (PCR) associated to the enrichment culture, and to determine the antimicrobial susceptibility patterns of isolat...

objective(s) rapid tests for detection of streptococcus agalactiae or group b streptococci (gbs) at the onset of labor are needed to permit early intrapartum antibiotic prophylaxis. this study aimed to evaluate the pcr assays targeting the 16s ribosomal rna gene (16s rdna) for detection of the gbs in comparison with a specific culture method. materials and methods two swabs were used to obtain ...

OBJECTIVE To estimate the prevalence of group B Streptococcus (GBS) carriage among pregnant women attending the antenatal clinic, and the colonization rates among newborn born to colonized mothers. MATERIAL AND METHODS Women attending the antenatal clinic between 35-37 weeks were screened using rectal and lower vaginal swab. Swabs were initially plated on sheep blood agar and LIM broth. The L...

Streptococcus agalactiae or Group B (GBS) is an important pathogen, which can cause serious illness and sometimes death especially in newborns, pregnant women people with compromised immune system. The major risk factor for neonatal disease vaginal colonization of GBS during pregnancy delivery. 1) To study the incidence among women. 2) compare efficacy sheep blood agar vs selective medium like ...

OBJECTIVE The purpose of the present study was to explore the direct effects of amnion and chorion on bacterial growth in vitro including the antibacterial spectrum. Chorioamniotic membranes were obtained under sterile conditions from 13 healthy women undergoing elective cesarean section at term. Likewise, chorioamniotic membranes were obtained from 10 healthy women with spontaneous vaginal del...

Previous published reports have shown that group B Streptococcus (GBS) isolates were 100% susceptible to both penicillin (1, 2) and vancomycin (1); however, reduced susceptibilities to penicillin have been documented (3–8). GBS susceptibilities to clindamycin and erythromycin have varied (2, 9–12), and data regarding inducible clindamycin resistance are not always reported (2). We examined GBS ...

Objective(s) Rapid tests for detection of Streptococcus agalactiae or Group B Streptococci (GBS) at the onset of labor are needed to permit early intrapartum antibiotic prophylaxis. This study aimed to evaluate the PCR assays targeting the 16S ribosomal RNA gene (16S rDNA) for detection of the GBS in comparison with a specific culture method. Materials and Methods Two swabs were used to obtain ...

Pigment production by group B streptococci (GBS) is a useful test for identification of the organisms. The test is positive in 99.5% of beta-haemolytic strains. No false-positives are noted. Non-haemolytic strains do not produce pigment. Islam's media less agar can be used as a one-step broth detector of GBS in mixed cultures. This may have application for the detection of GBS in women in labou...
